EF-S 18-55mm IS II review: http://www.the-digital-picture.com ….6-IS-II-Lens-Review.aspx
As I said in the beginning of the Canon EF-S 18-55mm f/3.5-5.6 IS II Lens review, the "II" replaces the "I". "The version II of this lens includes new IS algorithms to distinguish between normal photographing and when the camera is panning to automatically provide the optimal level of image-shake correction."
They were just repeating what they read in the Canon Press release of Feb 07 2011 http://www.usa.canon.com …il&docId=0901e0248028433f
The version II of this lens includes new IS algorithms to distinguish between normal photographing and when the camera is panning to automatically provide the optimal level of image-shake correction.
Unfortunately, it is misleading because Version I of this lens also included the same "new IS algorithms to distinguish between normal photographing and when the camera is panning to automatically provide the optimal level of image-shake correction."
Aug 2007 Canon Press Release: http://www.dpreview.com …onefs18-55and55-250#press
Canon’s latest optical Image Stabilizer (IS) technology provides up to 4-stop compensation for image blur caused by camera shake and slow shutter speeds. Photographers normally shooting handheld at 1/250 sec can switch on IS to obtain a similarly steady and blur-free result with a shutter speed of just 1/15 second. The inclusion of automatic panning detection makes it easier for photographers to track wildlife and other moving subjects. To ensure consistently accurate results at all zoom positions, the IS system within each lens has been optimised for that lens’ specific focal length range. Since the IS system is based within the lens, the results are visible through the viewfinder when framing the image.
